I don't know what's worse; making crosswords with only SQL related questions (requires free registration to access) or actually trying to solve the same. This is one of many thing that currently puzzles me. One other thing that also scares me is that I get annoyed when I cannot solve these crosswords right away...
Would like to access the crosswords
So why don't you register on that site? It is free. All this stated right after the link in my post... ("requires free registration to access")
